The North Central Valley Regionof California, including the California Delta, has weather that is hot and dry in the summertime, and wet and cool in the wintertime. Summers consist of low humidity levels, and occasional temperatures that climb above the 95-degree mark. In the Delta Area, where the Sacramento and San Joaquin Rivers meet, humidity is a little higher. Thunderstorms are possible anytime of the year, but they are usually light and infrequent. Rain is almost non-existent in summertime in the valley. In winter, the Pacific high that keeps storms at bay in summer retreats southward, bringing widespread, moderate precipitation to the area. Also in winter, a shallow layer of ground fog, known as "tule fog," frequently forms at night and can persist for two or three weeks. Flooding in winter results when rain is heavy over a period of one or two days.
